Resurgence in Mathematics and Physics

The aim of the conference is to facilitate an interaction between mathematicians and physicists interested in the phenomenon of resurgence, when apparently divergent series correspond to germs of analytic functions in sectors via Borel summation.

We hope that such interaction will bring new ideas in both subjects explaining e.g. analyticitity with respect to various perturbative parameters in physics, convergence of instanton corrections in symplectic topology,  the role of the wall-crossing formulas in resurgence, etc.

The conference « Reductive groups and automorphic forms » marks the closing of the European Research Council project « Arithmetic of automorphic motives, » (AAMOT) and it is dedicated to the French school of automorphic forms and to the colleagues who have contributed to its vitality over many decades. We find it especially appropriate to dedicate the conference to the memory of Roger Godement, who passed away on July 21, 2016, and whose early and consistent commitment was of such importance in establishing Paris as a major international center in the Langlands program and in the theory of automorphic forms more broadly understood.

Combinatorics an Arithmetic for Physics: special days

The meeting’s focus is on questions of discrete mathematics and number theory with an emphasis on computability. Problems are drawn mainly from theoretical physics (renormalisation, combinatorial physics, geometry) or related to its models. Computation, based on combinatorial structures (graphs, trees, words, automata, semirings, bases) or classic structures (operators, Hopf algebras, evolution equations, special functions, categories) are good candidates for computer-based implantation and experimentation.

The workshop will address fundamental features that determine the efficiency and control of information flow on directed networks,information retrieval, including also such fundamental properties of Google matrix as the fractal Weyl law, Anderson localization transitionfor Google matrix eigenstates.

The highlights and future developments of this research fieldwill be analyzed 20 years after the seminal article of Brin and Page (1998).

*-Keywords: Markov chains, complex networks, Google matrix,  information and financial flows, Wikipedia and cancer networks, recommender systems
